What Is OASWITCH-MIB?

This is a vendor-specific MIB from OneAccess covering the integrated LAN switch functionality built into its CPE routers, managing switch port configuration, VLAN membership, and MAC address table (forwarding table) status. It exposes objects for clearing and sizing the MAC address information table, plus a detailed MAC table recording learned addresses, their VLAN ID, switch port, learning mode, and tagging status. Its monitoring value centers on the switch's software-level Layer 2 forwarding state: administrators check the MAC table size and entries to confirm expected devices are being learned on the correct ports and VLANs, useful for detecting port flapping, MAC address moves, or VLAN misconfiguration. It builds on general bridge/VLAN concepts akin to the IETF BRIDGE-MIB and Q-BRIDGE-MIB but is implemented as a OneAccess-specific module rather than those standards directly. It is deployed on OneAccess CPE routers with an integrated Ethernet switch, typically at branch or enterprise edge sites. Engineers can download the OASWITCH-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in OASWITCH-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Supported Devices

MRV Communications Optical Access (OA) platform

Monitoring Examples

An administrator checks oaSwitchMacInfoNumber against oaSwitchMacInfoMaxNumbr to see how full the MAC address table is, and can invoke oaSwitchMacInfoClear to flush stale entries. Walking oaSwMacTable reveals each oaSwMacAddr along with its oaSwMacVid (VLAN ID) and oaSwMacPort, useful for confirming a given device is learned on the expected port and VLAN. If a MAC address appears to be moving rapidly between oaSwMacPort values across successive polls, that points to a Layer 2 loop or duplicate MAC address on the switch.

What Can Be Monitored

MAC address table size/utilization
learned MAC address entries
VLAN ID per MAC entry
switch port per MAC entry
MAC tagging/learning mode

INT oaSwitchMacInfoClear	1.3.6.1.4.1.6926.1.5.1.1.5	INTEGER	read-write	GET always returns 'none (1)'. SET 'clear(2)' couses LT erasing. GET always returns 'none (1)'. WARNING: erasing LT on some kind of agents may couse disconnection for short period of time.
oaSwMacTable	1.3.6.1.4.1.6926.1.5.1.2		not-accessible	A table that contains Learning Table with fields that does not exsist in dot1dTpFdbTable.
oaSwMacEntry	1.3.6.1.4.1.6926.1.5.1.2.1		not-accessible	Information about a specific MAC address in the oaSwMacTable.
MAC oaSwMacAddr	1.3.6.1.4.1.6926.1.5.1.2.1.1	MacAddress	read-only	MAC address for which the bridge has forwarding and/or filtering information.
INT oaSwMacVid	1.3.6.1.4.1.6926.1.5.1.2.1.2	INTEGER	read-only	Tag of the entry: the address 'Address recognition' is concatenation of oaSwMac and oaSwMacVid. When ISVP is not implemented or ISVL mode is disabled, this field in SET/NEXT operations may have any value, GET operation should return 0.
INT oaSwMacVidx	1.3.6.1.4.1.6926.1.5.1.2.1.6	INTEGER	read-write	Outbound VLAN tag: if frame 'Address recognition' was resolved with this entry, the forwarding will be maked according the VLAN with this tag. When ISVP is not implemented or ISVL mode is disabled, this field in SET operations may have any value, GET operation should return 0.
INT oaSwMacGetViewIndex	1.3.6.1.4.1.6926.1.5.1.2.1.8	INTEGER	read-only	Sequantial index of the entry.
INT oaSwMacPort	1.3.6.1.4.1.6926.1.5.1.2.1.9	INTEGER	read-write	Port of the entry. '0' value indicates that the port number has not been learned but that the bridge does have some forwarding/filtering information about this address. Another words, the frame will be forwarding 'to the CPU only' and the bridge will sovle, what it must be done with this frame.
INT oaSwMacMode	1.3.6.1.4.1.6926.1.5.1.2.1.20	INTEGER	read-write	Status of the entry: Only 'dynamic (2)' entries are aged.
INT oaSwMacTagged	1.3.6.1.4.1.6926.1.5.1.2.1.21	INTEGER	read-write	'Tagged' state of the entry. When ISVP is not implemented or ISVL mode is disabled, this field in SET operations may have any value, GET operation should return 0.

INT oaSwMacStatus	1.3.6.1.4.1.6926.1.5.1.2.1.30	INTEGER	read-write	State of the entry: Only 'valid(1)' entries participate in the forwarding/filtering process. The new entry is created when PDU with oaSwMacStatus=valid(1), oaSwMac, oaSwMacVid and optionally oaSwMacPort (default '0'), oaSwMacVidx (default oaSwMacVid) and oaSwMacMode comes. If {oaSwMac,oaSwMacVid} exists, the bridge replaces it. The old entry is deleted when PDU with oaSwMacStatus=invalid(2), oaSwMac, oaSwMacVid comes. The old entry is modified when PDU with oaSwMac, oaSwMacVid and new value of fields oaSwMacPort and/or oaSwMacVidx and/or oaSwMacMode comes.

OCT oaSysFrmGenDestMap	1.3.6.1.4.1.6926.1.5.3.6	OCTET STRING	read-write	The Frame Generator Destination Map = the set of ports to which the generated packets are to be sent. Each octet within the value of this object specifies a set of eight ports, with the first octet specifying ports 1 through 8, the second octet specifying ports 9 through 16, etc. Within each octet, the most significant bit represents the lowest numbered port, and the least significant bit represents the highest numbered port. Thus, each port of the switch is represented by a single bit within the value of this object. If that bit has a value of then that port is included in the set of ports; the port is not included if its bit has a value of . (Note that the setting of the bit corresponding to the port from which a frame is received is irrelevant.) The default value of this object is a string of ones of appropriate length.
